Abstract :

Environmental stresses of drought and salinity of the most important causes of yield loss factors are high plants in the world. Salinity affects the growth of the different aspects and reduce and delay germination, vigor reduction, reduced growth and reduced aboveground dry matter production in throughput. Determination of seed vital medicinal plants against various stresses including salinity of the main factors in the success of mass cultivation of plants. The seed vigor three medicinal plants Arcitum lappa L., Artemisia absinthium L. and Cichorium intybus L. by salinity, 0, 100, 200, 300 and 400 NaCl mM was completely randomized design with four replications. Results show that the highest seed vigor in control of the species L. Cichorium intybus L. with 84.85 percent. But this trait of treatment with 300 mM onwards has been fixed and seed vigor almost to zero. L Cichorium intybus L. has the highest vigor and viability of Arcitum lappa L. the least vigor and germination is under salt stress.
